Title: Side lobe canceler
Inventor: KAWAAI TAKASHI
IPC: G01S7/36
Filed: 1988-07-29
Abstract: PURPOSE:To improve a suppression performance by a side lobe canceler circuit by correcting a difference in a time for reception between a main antenna and an auxiliary antenna, which is caused by an incident angle of an unnecessary wave. CONSTITUTION:An unnecessary interference wave entering from a side lobe of a main antenna 1 is delayed by a fixed delay time alpha in a delay circuit 21 and inputted as a signal (d) to a side lobe canceler (CSLC) circuit 100. Meanwhile, an unnecessary interference wave entering from an auxiliary antenna 2 is inputted as a reception signal (b) to a variable delay circuit 23. The circuit 23 is controlled by a delay control circuit 22 which detects a reception time difference D=A/C.cos theta due to interference wave arrival angles of a reception signal (a) of the main antenna 1 and the reception signal (b) of the auxiliary antenna 2, which is caused by a difference in position of installation between the main antenna 1 and the auxiliary antenna 2, and a delay time beta is set to be beta=alpha-D. By this constitution, an output signal (e) of the circuit 23 and the output signal (d) of the delay circuit 21 are inputted to the CSLC circuit 100 respectively without any time difference between them, and thereby a suppression performance of the circuit can be improved.

Abstract: PROBLEM TO BE SOLVED: To accurately measure the eccentricity of a continuous paper roll in a non-contacting state without man power by taking the picture of the whole end face of the paper roll with a photographing means and processing the taken picture. SOLUTION: A camera 4 which is the photographing means of an eccentricity measuring instrument is moved upward, downward, leftward, and rightward by means of actuators 5 and 6 in accordance with photographing positions. The camera 4 takes the picture of the whole end face of a continuous paper roll 1 at a position where the optical axis of the camera 4 roughly lies upon the axial line of the core 2 of the roll 1. Successively, the center of the core 2 is found by processing the taken picture of the core 2 and the maximum value and minimum value of the distance between the center of the core 2 of the roll 1 and one point on the outer peripheral line of the roll 1 are found. The eccentricity of the roll 1 is measured from the difference between the maximum value and minimum value.  When a digital camera having a large number of picture elements is used, in addition, the structure of the instrument becomes simpler and the measuring time can be shortened.

Title: Cross electromagnetic field amplifier tube
Inventor: SHINTANI MORIO
IPC: H01J25/50
Filed: 1987-07-31
Abstract: PURPOSE:To improve the stability of operation by making the electric field strength of the drift space of a circuit separator different from the electric field strength in the interaction space region of a low-speed wave circuit by at least 10% or more and suppressing unnecessary microwaves. CONSTITUTION:Microwaves inputted from an input microwave line 14 are amplified while proceeding to an output end 17 on a low-speed wave circuit 12. If the distance R3 between a circuit separator 22 and a cathode 11 is made larger than the value that the distance R2 between the cathode 11 and the low-speed wave circuit 12 is divided by 0.9, a difference of 10% or more occurs between the voltage strength E1 applied to the drift space region formed by the circuit separator 22 and the surface of the cathode 11 facing it and the voltage strength E2 applied to the interaction space region of the low-speed wave circuit 12. The electron drift speed is thereby decreased at the portion of the circuit separator 22, the condition of the unnecessary microwave oscillation is disturbed, and the oscillation is suppressed.

Title: Robot teaching program converting method
Inventor: NIHEI AKIRA
IPC: G05B19/416
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of vibration accompanying circular arc movement without lowering the velocity of circular arc movement by automatically fixing a proper teaching velocity concerning route movement of a circular arc designated by a robot teaching program. SOLUTION: An original teaching program to be a converting object is prepared in the memory of an off line programming device 40 or a nonvolatile memory 14 within a robot controller 10. Then converting processing is executed within the controller 10 or the device 40 to convert into a teaching program suppressing vibration. In this case the original teaching program is read to search the circular arc route to calculate a radius concerning the circular arc route. A teaching velocity value corresponding to the calculated radius is obtained from a table data to rewrite to a value obtaining the teaching velocity of each circular arc route designated by the original teaching program. A velocity table fixes the maximum allowable value of operable teaching velocity for each range of a radius from the view point of vibration generation prevention.

IPC: A61G5/02
Filed: 1988-08-02
Abstract: PURPOSE: To enable simple and safe operation without excessive force even indoors or in a more or less inclined path by providing the wheelchair with a propelling/speed-converting means manually operable by a user. CONSTITUTION: In a propelling means 3 one end of a connector rod 2 is connected with a propelling/speed-converting rod 12 by a fixing pin 11, and the other end is connected with a propellant lever 1 by a movable pin 6. The range of speed conversion can be semi-permanently adjusted by speed conversion adjusting holes 10 in the propelling/speed-converting rod 12. In case the connector rod 12 is connected with the outermost one of the three holes, the speed becomes the slowest to be suitable to an aged user. When the user performs a pushing and pulling action of the propellant lever 1, the connector rod 2 connected with the propellant lever 1 rotates the propelling/speed-converting rod 12 about the axle 13 of the main body.  Thereby, a cam/clutch 21 combined with the propelling/speed-converting rod 12 is rotated integrally and transmits the rotation force to a flywheel 23, to facilitate forward and backward motions.
